How do I make a installable mobile game from website?

Hi, I have a question...can I make a mobile game that will install automaticly on a mobilephone (or tablet) like on the various stores when U choose a game... but I would like to host it on my own site...so that if U go to the link it will install it on ur mobile phone ????

thanks

I can only say for Android, that you can host the unsigned .apk File, that anyone can download to his android phone and install it (Settings must be adjusted on the phone to allow such installations).

thank U ehm sorry ...stupid question.... where do I find the .apg file option to save ? and what do U mean with unasigned ?

thanks again
